Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Studies on post- partun oestrum in cross bred cows
    (Department of Animal Reproduction, College of Veterinary and Animal Sciences, Mannuthy, 1979) Suresan Nair, S P; KAU; Neelakanta Iyer, C P
    The object of the study was to find out the various reproductive parameters that influence the onset of post – partum oestrus in cross bred cows. With this object in view, a detailed investigation was undertaken in a herd of 115 cross bred cows of Jersey x Sindhi and Jersey x Local breeds belonging to the University Livestock Farm of the Kerala Agricultural University, Mannuthy during the period from February 1978 to March, 1979. After parturition, they were grouped into normal and abnormal calvers based on the normalcy of calving. All the cows were stall fed and were under identical conditions of feeding and management. The observations made and inferences drawn are summarised below: There were significant variations in the cessation of lochial discharge, regression of pregnancy corpus luteum, period of uterine and vulval involution, onset of first and second ovulations and the post – partum oestrus interval between normal and abnormal parturitions. Duration of lochial discharge, regression of pregnancy corpus luteum and onset of first ovulation were found to be significantly influenced by the season of calving. Parity of the cow was found to influence the period of lochia, involutions of uterus and also the post – partum oestrus interval. Milk yield of the cow significantly influenced regression of pregnancy corpus luteum and vulval involution. However, the breed of the cow and sex and weight of calf were not found to have any significant effect on the reproductive parameters studied. An incidence of 13.4 per cent of aberrations of oestrum was also observed.

    Superovulation, Sychronisation of oestrus and embryo transfer in crossbred cows
    (Department of Animal Reproduction, College of Veterinary and Animal Sciences, Mannuthy, 1992) Suresan Nair, S P; KAU; Neelakanta Iyer, C P
    The object of the present investigation was to ascertain the influence of varying doses of FSH and PGF2₻on various parameters of superovulation and embryo collections, with the ultimate aim of fixing the optimum dose of FSH and PGF2 ₻ required for successful superovulation in crossbred cows. Detailed investigation was made in a herd of 32 crossbred cows belonging to the University Livestock Farm, attached to the College of Veterinary and Animal Sciences, Mannuthy, during the period from April 1989 to December, 1991. The animals were randomly divided into 6 groups based on 3 doses of FSH and 2 doses of PGF2 ₻ administered. It was observed that 20 mg of FSH, with 25 mg of PGF2 induced satisfactory superovulation response and 20 mg of FSH with 15 mg of PGF2 ₻ resulted in better embryo quality. Further increase in the dose did not show any improvement in the responses. Right ovary showed more response than the left. Day 11 was found to be ideal for starting superovulation treatment, and day 6 for embryo collection, though statistically no significant influence was noticed by day of collection on superovulation response. Parity and age of donors had no influence on superovulation. Rainy and summer months were found to be better seasons for superovulation treatment than winter. Shorter duration (24 hr) of oestrum was noticed in more number of animals. 20 mg of FSH and 25 mg of PGF2 ₻ (group 3) yielded better cervical dilatation and flushing efficiency. Level of progesterone increased following superovulation treatment and declined 3 days before oestrum and reached the lowest level on day of oestrum. Pregnancy rate achieved was 33.3 per cent, but calving percentage was nil.
